<div style="margin-left: 2em">
<h4><b>Version 2.1</b></h4>
<ol>
<li><tt>04.05.2002 fixed a problem with xpa contour load.</tt></li>
<li><tt>04.22.2002 ds9 version 2.1 released to the public.</tt></li>
</ol>
<h4><b>Version 2.1b7</b></h4>
<ol>
<li><tt>04.02.2002 upgrade to XPA 2.1.0e2. This fixes a problem with xpa and linux/linuxppc.</tt></li>
<li><tt>04.03.2002 fixed a problem with AST. plot.c, line 19463, change parameter 'force' from 1 to 0 in call to 'CheckLabels'. Sometimes we were seeing adj labels that where the same. This change makes sure that the labels are 'reduced' if we have this condition.</tt></li>
<li><tt>04.03.2002 ds9 will now automatically open as a bin table fits extension named EVENTS, STDEVT, and RAYEVENT.</tt></li>
<li><tt>04.03.2002 when trying to find an image to open in relax mode (ie the use did not specify an extension), ds9 will not find a valid image if the length of either axis is 0.</tt></li>
<li><tt>04.03.2002 now check for Ghostscript version 6.50 or higher when invoking Save As.</tt></li>
<li><tt>04.03.2002 add help application preference. Users can now choose between Netscape and Mozilla as the prefered help application.</tt></li>
<li><tt>04.04.2002 ds9 version 2.1b7 released to the public.</tt></li>
</ol>
<h4><b>Version 2.1b6</b></h4>
<ol>
<li><tt>02.04.2002 upgraded to ast version 1.8.6. Modified ast to use sscanf() for all platforms except Darwin. Darwin uses astSscanf(), which works around a problem with sscanf() on MacOSX, with format strings of the following format: sscanf(str, " %s %n", foo, &nc).</tt></li>
<li><tt>02.04.2002 changed fity++ primary_/head_ header relationship. primary_ is only set if there is a primary header is available and different from head_.</tt></li>
<li><tt>02.04.2002 wsc's are init'd with both the head_ and the primary_ (if available) to handle the case where wcs keywords are spread between hdu nd primary headers in mulitiple extension files.</tt></li>
<li><tt>02.06.2002 all xpa commands are now 'catch{}' to invoke a procedure that will unwind the watch cursor stack. Hopefully, no more stuck watch cursors.</tt></li>
<li><tt>02.07.2002 add <i>color</i> and <i>width</i> parameters to contours paste command. defaults are <i>green</i> and <i>1</i></tt></li>
<li><tt>02.08.2002 fixed a problem with the FRAME menu. It was cutting off the last separator.</tt></li>
<li><tt>02.12.2002 AST grid still does not support ICRS properly. When a user sets the coordinate system to ICRS, the actually parameters sent to the AST grid code is FK5</tt></li>
<li><tt>02.13.2002 for XPA points array, fits, regions, and wcs (fillbuf=false), manually flush the buffer at the end to make sure no data is left</tt></li>
<li><tt>02.13.2002 ecliptic coords from wcssubs corrected by new version of wcs/wcscon.c</tt></li>
<li><tt>02.13.2002 AST grids, corrected the MDJ-OBS keyword generated to generate the correct EPOCH.</tt></li>
<li><tt>02.13.2002 adjusted the EQUINOX value for ECLIPTIC coords for ast grids to agree with wcssubs. Seems for ecliptic coords, wcssubs and ast use two slightly different interpretations of the EQUINOX value.</tt></li>
<li><tt>02.13.2002 fixed a problem with histogram equalization introduced in version 2.1b5.</tt></li>
<li><tt>02.14.2002 fixed a problem with titles in plot(stdin). We now take the first line, and starting from the end, pick off the dimension, x and y axis titles, and the remainder is taken as the plot title. It can contain spaces and special characters such as '[]'</tt></li>
<li><tt>02.14.2002 add 'Always create new plot' option to prefs</tt></li>
<li><tt>02.14.2002 add multiple analysis plots, unless prefs are unset</tt></li>
<li><tt>02.14.2002 change default annulus and panda to 1 annuli</tt></li>
<li><tt>02.14.2002 enable multiple array loads via blueplate dialog</tt></li>
<li><tt>02.14.2002 reset,append, and replace wcs now processes OBJECT keyword</tt></li>
<li><tt>02.15.2002 fixed a problem with grid format of degrees. Sometimes, the incorrect format would be used. This was corrected by up'ng the number of digits displayed to d.3</tt></li>
<li><tt>02.21.2002 upgraded to AST 1.8.7</tt></li>
<li><tt>02.21.2002 upgraded to WCS 3.0.7</tt></li>
<li><tt>02.22.2002 fixed a problem with Ascii Tables in fitsy++. The column offset is now calculated from TBCOLn if present.</tt></li>
<li><tt>02.22.2002 simplied columns in fitsy++. Now all columns have a value(char* ptr, int i) and str(char* ptr, int i) procedure.</tt></li>
<li><tt>02.22.2002 add support for HST WFPC2 mosaics</tt></li>
<li><tt>02.25.2002 fixed a problem with 'marker command'. The command STRING must be quoted by '\{' '\}' before being pasted to the Frame parser.</tt></li>
<li><tt>02.26.2002 add $ERROR/ERROR: support for analysis $plot(stdin) macro.</tt></li>
<li><tt>02.26.2002 analysis menus now support multiple levels of hierarchical menus</tt></li>
